Abstract

Processing zinc and iron oxide-contg. residues involves (a) granulating the residue dust and/or sludge with water and charging, together with carbonaceous material, into a circulating fluidised bed system; (b) passing the circulating gas/solids suspension into a second fluidised bed; (c) returning the solids, discharged from the second fluidised bed, into the circulating fluidised bed reactor; (d) introducing 50-75 vol.% of the oxygen, required for gasification of the carbonaceous material, as fluidising gas into the reactor and 25-50 vol.% of the oxygen as fluidising and secondary gas into the second fluidised bed; and (e) discharging iron oxide-contg. material from the reactor and zinc-contg. material, together with off-gas, from the circulating fluidised bed system.
